JESSE C. SIMMONS, OF SHELBY, MICHIGAN.

BURNER FOR I-IYDROCARBON FUEL.

To all whom it may concern:

Be it known that I, Jnssn C. SIMMONS, a citizen of the United States, residing at Shelby, in the county of Oceana, State of Michigan, have invented certain new and useful Improvements in Burners for Hydrocarbon Fuel, of which the following is a specification.

This invention relates to improvements in burners for hydrocarbon fuel, such as kerosene, crude oil or the like, the samebeing an improvement on the burner illustrated and described in my application, Serial No.

7 50,276, which was allowed August 25, 1913. The objects of the invention are: First, to insure in a burner of this type thorough preheating of the fuel and complete gasification thereof before delivering to the burner tips. Second, to provide a burner of this type, the parts of which are readily accessible for the purpose of cleaning. Third, to provide a burner which will prevent the gathering of carbon deposits from the fuel. Fourth, to provide in a burner of this type an improved construction of pilot burner.

Further objects, and objects relating to details and to economies of construction and operation will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure constituting a preferred embodiment of my invention is clearly illustrated in the drawing forming a part of this specification, in which- Figure I is a plan view of the burner embodying my improvement.

Fig. VIII is an elevation .view showing the connection between the fuel delivery pipe and the generator tube. F1g. IX is,a sectional view on the line 99 of Fig. I, showingthe inlet to the generator tube in detail. Fig. X is a perspective view of the pilot burner. Fig. XI is a sectional view on the line 1111 of Fig. X. Fig. XII is a detail sectional view on the line 1212 of Fig. VI, showing the manner in which the pilot burner is secured to the burner head.

In the drawing the sectional views are taken looking in the direction of the little arrows at the ends of the section lines, and similar numerals refer to similar parts throughout the several views.

Considering the numbered parts of the drawing, the main burner case 1 is provided with a double bottom structure, the upper portion 2 of which is corrugated and slitted to form the burner head, as clearly shown in Figs. I, II and VII. Fuel is supplied to the burner through the feed pipe 3, which consists of a series of parallel lengths lying in the troughs of the corrugated burner head 2, and connected at the ends by the upwardly curved sections 4, 4 and 4". The

upwardly curved sections serve as traps to hold the ungasified liquid fuel in the straight sections 3 which are exposed to the most intense heat. It will be noted that these parallel sections lie in the troughs of the corrugated burner head and are at the level of the lowest portion of the slits in the burner head 2 where they do not rob the boiler of any heat but use that which would otherwise go to waste. The end of the delivery tube passes through the side of the burner case 1 and is connected with the downwardly curved section 5. This section 5 is connected to the block 6 by means of the coupling 7.

Block 6 contains a Y shaped passage consisting of the main passage 8 and branches 10. These branches 1O communicate with to the main portions of the delivery tube 3, and a short distance above the top of the burner head so that they are located approximately in the hottest part of the flame therefrom. The opposite ends of said generator tubes are fixed in the head block 12 which contains the passages 11 communicating with said tubes and extending upwardly therefrom. These passages communicate with the vertical passages 13 formed in the arms 15 which carry the main burner nozzles 14-. These nozzles 14 each deliver a jet under strong pressure into one mixing tube 16 of the main burner. These mixing tubes 16 fit tightly into the burner casing and ex tend well. toward the center thereof so that the fuel mixture will be delivered out under the burner head plate and flow up evenly through all the slits of the burner. These tubes are each provided with a flaring funnel shaped mouth 17 which extends laterally for a considerable distance at one side and is practically in alinement with the wall of the tube on the side nearest the center of the burner. The object of this funnel shaped mouth is to prevent air being sucked into the mixing tubes from around the intake for the pilot burner and thus robbing the pilot burner of its air.

Numeral 19 designates the pilot burner generator tube which enters the bottom of the burner case 1 near the center thereof, as shown at 19, and is disposed a little above the main generator tubes and parallel thereto. The end of this tube is fixed in head block 12. A passage 20 is provided in block 12 communicating with the end of generator tube 19 and extending upwardly therefrom. Passage 21 communicates with passage 20 and extends downwardly therefrom into the bore 22 in arm At the lower end of arm 23 is the pilot burner valve 24 which is screw threaded and has a needle point 25 for controlling the delivery of the fuel into the mixing tube 26 leading into the pilot burner 28. This mixing tube is a cylindrical tube provided with a series of perforations 27 in the bottom thereof. The pilot burner consists of a W-shaped tube suitably slitted at the top and provided at the rear with a depending lip 29 which carries the inner end of the mixing tube 26. The pilot burner 28 is secured to one of the troughs of the burner head by means of bolts 30. The outer end of this burner is forked and the branches 31 thereof are suitably slitted and provided with passages 32 by which the gas is led into the branches. The purpose of this portion of the pilot burner to allow the same to extend beneath the head block 12 so that the block may be kept heated at all times.

Numeral 33 designates the front plate which closes the opening in burner case 1, through which the mixing tubes are invery readily understood.

serted. This plate also supports the end of burner 28. There is also provided the casing 34 covering the head block 12. This casing is provided with a rearwardly extending lip 34:, and is secured to the case 1 as at 85. The casing is secured to the block 12 by means of the bolt 36 threaded therein. At the front is provided the window 37 having a pane of mica 38 therein and pivoted at one side as at 37. This window serves to permit inspection of the pilot and also to allow the introduction of the starting torch at this point.

From the description of the parts above given, the operation of the structure will be The course of the fuel is as follows: From the main supply tank the fuel enters the delivery tube 3,

flows through upwardly curved section 4:,

tube 8, upwardly curved section 4, tube 3,

upwardly curved section 4", through tube and out through downwardly curved section 5, through the passage 8 and thence through the passages 10 mto the generator tubes 9. From the generator tubes 9 the gas passes through the passages 11 and 13 to the burner nozzles 14, whence it is delivered in a jet to the mixing tubes 16 from which it flows out beneath the burner head 2. The fuel for the pilot burner enters the generator tube 19, flows through passagesv 20, 21 and 22 and passes through the needle valve '25 into the mixing tube 26 from which the gas is delivered to the pilot burner 28.

In the burner as I have made use of it the liquid fuel has been delivered at a com paratively high pressure, varying from thirty-five to a hundred pounds, by the usual pressure means supplied on an automobile, for instance, and the parts here shown are of the proportions of such parts.

The pilot burner supply and the main burner supply are connected to the same pressure tank. The usual torch is introduced through the window 37 and the pilot is then started after generation begins. This immediately heats up the main generator tube and. the head block and after two or three minutes operation of the pilot the full burner is ready to start. By this arrangement of the heating and generating tubes I, avoid all deposits of carbon and insure a very thorough preheating of the before it is delivered to the burner. iviy improved burner is here shown adapted to ai'itomobile use, and especially to an automobile burner.

The invention is applicable to any kind or style of a tubular or flat topped burner, and I do not wish to be understood as restricting my broader claims to the particular form. of burner which I have here illustrated, as any form can be made use of in this behalf. A sawed burner or a bored burner is equally available. The particular arrangement of the parts I have here shown is especially effective and I desire to claim the same specifically as well as broadly, as indicated by the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
